When I built up my wooden shelves, I deliberately made the first shelf just the right height that the front wheels reach the shelf while the rears are on the ground.
The only mowers I can lift above waist height is the little 16inch ones. Can lift a regular mower into the boot of a car easily enough. Problem in my case is due to a severe hereditary bone spur condition, I can't even squat lift anymore - a pointy spur (bone tumour) goes through the muscle about 3 inches above the left knee. I literally ran 5 steps 2 months ago, pierced it and fell down - couldn't walk for days. Pair that with the one under my left armpit (also pointy - can't lift my arm over my head if holding any weight) and it makes moving things around a real issue.
Whenever I squat or kneel down or get up, I am forever careful because it will just grab - fell over getting up from cleaning out a sprinkler head on sunday.
I am starting to know how Norm felt before the hip replacement a few years back.
I see guys lifting 17in sb45 mowers in and I just cringe
